A Denial of Service vulnerability exists in FFmpeg 4.2 due to a memory leak is affected by: memory leak in the link_filter_inouts function in libavfilter/graphparser.c.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-936095 advisory.

    A Denial of Service vulnerability exists in FFmpeg 4.2 due to a memory leak is affected by: memory leak in     the link_filter_inouts function in libavfilter/graphparser.c.

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - FFmpeg <=4.3 contains a buffer overflow vulnerability in libavcodec through a crafted file that may lead
    to remote code execution. (CVE-2021-30123)

  - FFmpeg 4.2 is affected by null pointer dereference passed as argument to libavformat/aviobuf.c, which
    could cause a Denial of Service. (CVE-2020-20450)

  - Buffer Overflow vulnerability exists in FFmpeg 4.1 via apng_do_inverse_blend in libavcodec/pngenc.c, which
    could let a remote malicious user cause a Denial of Service (CVE-2020-21041)

  - A Denial of Service vulnerability exists in FFmpeg 4.2 due to a memory leak in the
    ff_v4l2_m2m_create_context function in v4l2_m2m.c. (CVE-2020-22038)
